This is an amazing cooktop when it works. It heats up quickly, cools down quickly - fantastic! However I just registered my SECOND one with GE because 3 out of 5 burners stopped working after only 17 months!! I heard a loud POP and that was that. Luckily I purchased a warranty. The warranty company chose to purchase us a new cooktop rather than fix the broken one. An interesting choice that I don't totally understand. I am concerned that our new second cooktop will go POP in 17 months and I will be out a cooktop and $1500. So....GREAT cooktop. Buy a warranty for sure. GE - please fix this issue! You have an amazing product here but it needs to last many  years for the cost!
